IPv6 packet may carry more than one extension header, and IPv6 nodes must
accept and attempt to process extension headers in any order and occurring
any number of times in the same packet. Hence, there should be no
assumption that Segment Routing extension header is to appear immediately
after the IPv6 header.
Moreover, section 4.1 of RFC 8200 gives a recommendation on the order of
appearance of those extension headers within an IPv6 packet. According to
this recommendation, Segment Routing extension header should appear after
Hop-by-Hop and Destination Options headers (if they present).
This patch fixes the get_srh(), so it gets the segment routing header
regardless of its position in the chain of the extension headers in IPv6
packet, and makes sure that the IPv6 routing extension header is of Type 4.

net: mvpp2: comphy configuration
This series, following up the one one the GoP/MAC configuration, aims at
stopping to depend on the firmware/bootloader configuration when using
the PPv2 engine. With this series the PPv2 driver does not need to rely
on a previous configuration, and dynamic reconfiguration while the
kernel is running can be done (i.e. switch one port from SGMII to 10G,
or the opposite). A port can now be configured in a different mode than
what's done in the firmware/bootloader as well.
The series first contain patches in the generic PHY framework to support
what is called the comphy (common PHYs), which is an h/w block providing
PHYs that can be configured in various modes ranging from SGMII, 10G
to SATA and others. As of now only the SGMII and 10G modes are
supported by the comphy driver.
Then patches are modifying the PPv2 driver to first add the comphy
initialization sequence (i.e. calls to the generic PHY framework) and to
then take advantage of this to allow dynamic reconfiguration (i.e.
configuring the mode of a port given what's connected, between sgmii and
10G). Note the use of the comphy in the PPv2 driver is kept optional
(i.e. if not described in dt the driver still as before an relies on the
firmware/bootloader configuration).
Finally there are dt/defconfig patches to describe and take advantage of
this.
This was tested on a range of devices: 8040-db, 8040-mcbin and 7040-db.
@Dave: the dt patches should go through the mvebu tree (patches 9-13).
Thanks!

- Kept the link mode enforcement.
- Removed the netif_running() check.
- Reworded the "dynamic reconfiguration of the PHY mode" commit log.
- Added one patch not to force the GMAC autoneg parameters when using
the XLG MAC.
Since v1:
- Updated the mode settings variable name in the comphy driver to
have 'cp110' in it.
- Documented the PHY cell argument in the dt documentation.
- New patch adding comphy phandles for the 7040-db board.

This patch adds logic to reconfigure the comphy/GoP/MAC when the link
state is updated at runtime. This is very useful on boards where many

Using current TC code, it is very slow to insert a lot of rules.
In order to improve the rules update rate in TC,
we introduced the following two changes:
1) changed cls_flower to use IDR to manage the filters.
2) changed all act_xxx modules to use IDR instead of
a small hash table
But IDR has a limitation that it uses int. TC handle uses u32.
To make sure there is no regression, we add several new IDR APIs

Typically, each TC filter has its own action. All the actions of the
same type are saved in its hash table. But the hash buckets are too
small that it degrades to a list. And the performance is greatly
affected. For example, it takes about 0m11.914s to insert 64K rules.
If we convert the hash table to IDR, it only takes about 0m1.500s.
The improvement is huge.
But please note that the test result is based on previous patch that
cls_flower uses IDR.

Currently, all filters with the same priority are linked in a doubly
linked list. Every filter should have a unique handle. To make the
handle unique, we need to iterate the list every time to see if the
handle exists or not when inserting a new filter. It is time-consuming.
For example, it takes about 5m3.169s to insert 64K rules.
This patch changes cls_flower to use IDR. With this patch, it
takes about 0m1.127s to insert 64K rules. The improvement is huge.
But please note that in this testing, all filters share the same action.
If every filter has a unique action, that is another bottleneck.

net: Add support for rmnet driver
This patch series adds support for the rmnet driver which is required to
support recent chipsets using Qualcomm Technologies, Inc. modems. The data
from hardware follows the multiplexing and aggregation protocol (MAP).
This driver can be used to register onto any physical network device in
IP mode. Physical transports include USB, HSIC, PCIe and IP accelerator.
rmnet driver helps to decode these packets and queue them to network
stack (and encode and transmit it to the physical device).
v1: Same as the RFC patch with some minor fixes for issues reported by
kbuild test robot.
v1->v2: Change datatypes and remove config IOCTL as mentioned by David.
Also fix checkpatch issues and remove some unused code.
v2->v3: Move location to drivers/net and rename to rmnet. Change the
userspace - netlink communication from custom netlink to rtnl_link_ops.
Refactor some code. Use a fixed config for ingress and egress.
v3->v4: Move location to drivers/net/ethernet/qualcomm/.
Fix comments from Stephen and Jiri -
Split the ether and arp type changes into seperate patches.
Remove debug and custom logging and switch to standard netdevice log.
Remove module parameters. Refactor and change some code style issues.
v4->v5: Rename some structs and variables. Move the initializer
before the for loop start. Put the arp type in correct sequence.
v5->v6: Fix comments from Dan -
Use the upper link API. As a result, remove all the refcounting logic.
Device refcount is explicitly held on real_dev on rx_handler
registration only. Modifiy the flow control struct. Remove the unused
ethernet mode handling.
v6->v7: Fix comments from David - Add newline to end of Makefile. Remove
inline from .c files. Move the module init/exit to rmnet config. Fix an
error reported by kbuild test robot for an unused file.
v7->v8: Use a smaller value for ETH_P_MAP as mentioned by David. Change
netdev_info to netdev_dbg as mentioned by Andew. Fix comments from
Stephen regarding netdev_priv and sparse related errors of using 0 as NULL
v8->v9: Fix comments from David - Remove the CFLAG rule. Change the way

individually, go through the list and free all devices within the rtnl_lock().
v9->v10: Actually fix the locking as mentioned by David. The locking scheme is

There is a difference in the bit position of the normal interrupt summary

of the hardware. For older revisions the NIE and AIE bits are positions
16 and 15 respectively. For newer revisions the NIE and AIE bits are
positions 15 and 14. The effect in changing the bit position is that
newer hardware won't receive AIE interrupts in the current version of the
driver. Specifically, the driver uses this interrupt to collect
statistics on when a receive buffer unavailable event occurs and to
restart the driver/device when a fatal bus error occurs.
Update the driver to set the interrupt enable bit based on the reported
